A signal separation method based on the subarray beam synthesis

IET Radar, Sonar & Navigation, 2023
Large‐scale arrays are widely used due to their advantages of high gain, high resolution, and strong beam control capability. The large number of antennas leads to a sharp increase in computational complexity, and thus, it is necessary to reduce the ...

Nonconvex Regularization-Based Sparse Recovery and Demixing With Application to Color Image Inpainting

IEEE Access, 2017
This paper addresses the recovery and demixing problem of signals that are sparse in some general dictionary. Involved applications include source separation, image inpainting, super-resolution, and restoration of signals corrupted by clipping ...

Underdetermined noisy blind separation using dual matching pursuits [PDF]

, 2004
Underdetermined blind source separation is a key application in audio where it is desirable to extract multiple sources from a stereo recording. A new variant on the stereo matching pursuit, the dual matching pursuit, is presented whereby independent ...

Stable Recovery and Separation of Structured Signals by Convex Geometry

IEEE Access, 2022
We consider the ill-posed problem of identifying the signal that is structured in some general dictionary (i.e., possibly redundant or over-complete matrix) from corrupted measurements, where the corruption is structured in another general dictionary. We
